Eagle Chevy 454 4.000in Crank 6.135in I-Beam Rods 43cc Dome 4.250in Pistons Balanced Assembly

Eagle has a solid reputation for making well-built performance engine components, and this balanced rotating assembly for the Chevy 454 is a prime example. If you're building a naturally-aspirated racing engine, this assembly is designed to handle the demands of that kind of use. It’s a complete package that takes the guesswork out of matching critical internal engine parts.

At the heart of this assembly is a 4.000-inch forged 4340 crankshaft, chosen for its strength and durability under high stress. Paired with it are 6.135-inch I-beam connecting rods, also made from robust 4340 steel, and secured with 7/16-inch ARP 8740 bolts. These components are built to withstand the forces generated in a performance engine. The assembly includes 4.250-inch forged 2618 pistons from ICON, featuring a 43cc dome shape that's common in many performance builds. These come with plasma-moly file-fit rings, allowing for precise gap setting to optimize sealing and performance. To ensure smooth operation and longevity, the assembly is completed with King XP rod and main bearings, known for their reliable performance.

This rotating assembly comes balanced from the factory, which is a crucial step for reducing engine vibration and improving overall smoothness and lifespan. This balanced assembly is intended for racing applications and is not CARB approved, meaning it cannot be shipped to California. Please ensure this fits your specific build requirements before ordering.
